My Ender 3 Printer was working fine before, but recently an error Thermal Runaway E1 has been showing up and halting my prints, really in the first couple of minutes.
I have done a bit of research and :
- I replaced the Thermistor
- I ran a PID autotune via Pronterface, which worked fine 2 out of the 3 times I attempted this.
After these changes, I still sometimes get Thermal Runaway E1 Error, and most other times I get ‘Heat Failure’ E1. It seems that the problem is in the nozzle temperature, and for some reason the temperature stops increasing about ten degrees from the temperature that it is set to reach.
If I set the nozzle temperature at 240 degrees,
The nozzle will start decreasing temperature at about 230 degrees, and the
‘Heat Failure’ error will be triggered.
If I set the nozzle temp at 220 degrees, The nozzle will start decreasing temperature at about 210 degrees, and the 'Heat Failure' error will be triggered.
Has anyone else had this issue with Ender 3? I keep checking wires to see if that’s the issue, but it all looks fine, everything is attached to the right spots and secure. The nozzle does get hot, so I don’t think my heat cartridge is the problem. I’ve changed the thermistor twice, so I don’t think that’s the issue either. I feel like it must be something off in the calibration (my printer came with Marlin), but I’m not sure how to change that.
Any help would be much appreciated!
